Recently I've got a report of BUG_ON trigerring during transaction commit in ext4_journalled_writepage_callback() because we've spotted a dirty page without buffers. Add WARN_ON_ONCE to ext4_journalled_set_page_dirty() to catch the problematic condition earlier where we have better chance of understanding which code path is creating dirty data without preparing the page properly. Also update the comment with current information when we are at it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
